The Cisco IOS XR Broadband Network Gateway Implementation and Verification (IOSXR304) is an instructor-led or virtual instructor-led course that teaches you how to successfully deploy, configure, operate, maintain, and support a Cisco IOR XR Broadband Network Gateway (BNG) solution.

This course will show you how to implement and verify BNG on a Cisco IOS XR device to manage subscriber access. You will also learn how to implement and verify subscriber management functions, including authentication, authorization, and accounting of subscriber sessions, address assignment, security, policy management, and Quality of Service (QoS).


Upon completion of this course, you will be able to:
  • Describe the architecture and function of the Cisco IOS XR Broadband Network Gateway
  • Configure and verify Authentication, Authorization, and Accounting (AAA) in a Broadband Network Gateway deployment
  • Define policies to control subscriber traffic
  • Establish and verify subscriber sessions
  • Prioritise subscriber traffic using QoS
  • Implement subscriber features
  • Deploy redundancy for subscriber sessions
